Provided is an LED lamp using a switching circuit, which prevents an electric shock caused by contact with a human body or conductive metal by arranging the switching circuit between a first rectifier circuit and an LED circuit. The LED lamp using the switching circuit connects the switching circuit to at least one line among a plurality of lines connecting the rectifier circuit and LED circuit. The switching circuit includes: a switching device including at least one among an SCR, a TRIAC, a TR, and a FET; and a driving device including at least one among a condenser, a TVS, a SIDAC, a resistor, and an inductor.
